The difference between vacuum drying oven and precision blast drying oven

Vacuum drying ovens and blast drying ovens are two commonly used drying equipment. As we all know, to dry the dry material, it is only by direct heating, vacuuming and vacuuming to achieve the purpose of drying. However, what is the difference between a vacuum drying oven and a precision blast drying oven?

Through the direct heating method, of course, there is also a blast-assisted air assisting method, which is to make the material get the material quickly by moving the moisture, solvent or volatile component molecules in the material to make the molecules move quickly to get rid of the dry material. dry. Its drying speed can be very fast and the drying temperature can be very high. In particular, the precision blast drying oven, under the action of the fan, rapidly removes the volatile matter molecules volatilized from the surface of the material by air exchange, thereby achieving the function of rapidly drying the material.

The vacuum drying oven draws the space where the dry material is located into a vacuum by a vacuum pump, that is, a vacuum state. It is known that in a vacuum state or a low pressure state, the boiling points of moisture, solvent and other volatile components in the material are lowered, so that at a lower temperature, the surface of the material particles can be removed from the surface of the material particles and evacuated by a vacuum pump. Vacuum drying ovens are mainly used for materials that oxidize, polymerize and other chemical reactions at high temperatures. Of course, the vacuum drying oven also has the dual function of heating to accelerate the evaporation of moisture, solvent and volatile components to separate from the surface of the material.

The difference between the vacuum drying oven and the precision blast drying oven application is the stability of the chemical properties of the object of the user's dry material and the physical deformation of the dry material.
